Glyphs template: button to change style instead of scrolling

[RosaWagner]

I tend to remake the glyphset table in indesign so I can go in fullscreen mode and "animate" the next page and previous page to see exactly how one glyph change from a style to another. So I was thinking a button to navigate from a style to another in the Glyphs html template instead of scrolling could be nice.

Also the point-size button directly would be helpful.
